Vehicle-mounted antenna and coupling circuit therefor

摘要: Vehicle-mounted antenna system having a novel coupling circuit connected between the end of an lead-in cable away from latter''s connection to conventional standard broadcast and (A.M.) radio receiver citizens band communications equipment. This circuit: 1. PASSES STANDARD BROADCAST SIGNALS TO THE RECEIVER AND BLOCKS INCOMING CITIZENS BAND FROM THIS RECEIVER; 2. BETWEEN ANTENNA COMMUNICATIONS EQUIPMENT; 3. INCREASES EFFECTIVE ELECTRICAL LENGTH OF FOR EFFICIENT TRANSMISSION RECEPTION SIGNALS; 4. IMPEDANCE MATCHES LEAD-IN CABLE EQUIPMENT.
